Explanation:

does 9/20 and 18/30 form a proportion

Answers

Answer:

No, they don't.

Step-by-step explanation:

I'm going to divide 18 by 9 and 30 by 20. If the quotients are the same, then we do have a proportion.

18 ÷ 9 = 2

30 ÷ 20 = 1.5

The quotients aren't the same. Same thing if you convert the fractions to decimals:

9 ÷ 20 = 0.45

18 ÷ 30 = 0.6

This means the two values do NOT form a proportion.

Hope this helps! Have a great day!

Answer:

No.

Step-by-step explanation:

9/20=18/30

9*30=20*18

120=360

14d - 22 + 5d = 12d - 8

Answers

Answer:

d = 2

Step-by-step explanation:

14d - 22 +5d = 12d - 8

19d -22 = 12d - 8

      +22         +22

    19d = 12d + 14

  -12d   -12d

     7d = 14

    /7       /7

      d = 2

Answer:

d = 2

Step-by-step explanation:

Simplifying

14d + -22 + 5d = 12d + -8

Reorder the terms:

-22 + 14d + 5d = 12d + -8

Combine like terms: 14d + 5d = 19d

-22 + 19d = 12d + -8

Reorder the terms:

-22 + 19d = -8 + 12d

Solving

-22 + 19d = -8 + 12d

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-12d' to each side of the equation.

-22 + 19d + -12d = -8 + 12d + -12d

Combine like terms: 19d + -12d = 7d

-22 + 7d = -8 + 12d + -12d

Combine like terms: 12d + -12d = 0

-22 + 7d = -8 + 0

-22 + 7d = -8

Add '22' to each side of the equation.

-22 + 22 + 7d = -8 + 22

Combine like terms: -22 + 22 = 0

0 + 7d = -8 + 22

7d = -8 + 22

Combine like terms: -8 + 22 = 14

7d = 14

Divide each side by '7'.

d = 2

Simplifying

d = 2

Answers

Answer:

x = -31

Step-by-step explanation:

2(x-5) = 3(x+7)       1. Use distributive property

2x - 10 = 3x + 21     2.  Add 10 on both sides

2x = 3x + 31            3. Subtract 3x on both sides

-x = 31                       4. Divide by -1

x = -31

Solve the system of equations.
- 5y + 8x = -18
5y + 2x = 58
х=
y =

Answers

Answer:

x = 4 and y = 10

Step-by-step explanation:

-5y + 8x = -18

5y + 2x = 58

First you will want to get rid of y from both equations, so you add both equations together.

You will get 10x = 40, then subtract 10 from both sides and you get x = 4.

Now substitute x as 4 in any of the equations to get y.

-5y + 32 = -18

-5y = -50

y= 10

Answer:

x = 4

y = 10

Plug in each point into both equations to see which ones fit.

For the first point, (4,1) it works for both equations.

1=-2( 4 ) + 9, 1= -8 + 9, 1=1

4( 4 )+2( 1 )=18, 16 + 2 = 18, 18 = 18

Do it for the rest of the points and plug them in and you get,

no for (5,-3) because -1 does not equal to -3

no for (6,0) because -3 does not equal to 0

(-5,19) is yes because 19=19 and 18=18

Now, however, energy andenvironmental challenges are encouraging new building materials, new ways to design buildings, and new respect for nature.How would Mother Nature design a building?Through 4 billion years of evolution, organisms have come up with some neat designs. Architects are beginning to look to nature for cluesto building sustainabilityPerhaps most famous among biologically informed buildings is the Eastgate shopping center and office building in Harare, Zimbabwe. Thedesign was inspired by African termite mounds, where termites maintain a constant temperature of 87 degrees (to preserve a fungus that theycultivate to eat) by opening and closing flues that vent hot air.The concrete Eastgate building has no air-conditioning system. During the night, big fans draw cool outside air up through spaces betweenthe building's floors. During the day, smaller fans drive the warmer outside air through the same spaces, where the cool concrete moderates thetemperature. As the air warms, it rises through 48 round brick funnels and out the roof. Fresh air circulates through the building twice an hourduring the day. The building reportedly uses only 10 percent of the energy that a conventional building of the same size would use.How about building materials inspired by nature?
